Description

Technical Field

[0001] The present invention relates to the field of heated cigarette manufacturing, and more specifically, to an incompletely separated heated cigarette for paperless heating. Background Art

[0002] Traditional cigarettes release nicotine and flavor by directly burning tobacco to meet the needs of consumers. Tobacco will release many harmful substances during the high-temperature decomposition process. In recent years, as people's health awareness has increased, in order to avoid inhaling harmful substances released by high-temperature decomposition of tobacco, heat-not-burn cigarettes have emerged.

[0003] Heat-not-burn cigarettes use a matching external heat source to heat tobacco, obtaining nicotine and flavor without burning it. While meeting consumers' smoking needs, they have the characteristics of reducing tar and reducing harm compared to traditional cigarettes.

[0004] The tobacco segments of existing heat-not-burn cigarettes are wrapped with cigarette paper and inserted into the heating chamber of the smoking device for heating. When heated, the cigarette paper will produce a strong paper smell mixed into the smoke, affecting the purity of the smoke and further affecting the smoking experience of consumers. If the tobacco segments of heated cigarettes are set to be completely detachable from the heated cigarettes, it will lead to the problem that the tobacco segments are difficult to remove from the smoking device.

[0005] Therefore, how to provide a heated cigarette that can effectively prevent the smell of cigarette paper from affecting the smoke purity and in which the tobacco segments can be easily removed from the smoking device has become a technical problem that urgently needs to be solved in the art. Summary of the invention

[0006] One object of the present invention is to provide a new technical solution for paperless heating of incompletely separated cigarettes, which can effectively avoid the paper smell of cigarette paper affecting the smoke purity and make it easy to remove tobacco segments from smoking utensils.

[0007] According to a first aspect of the present invention, there is provided an incompletely separated heating cigarette for paperless heating.

[0008] The incompletely separated heated cigarette for paperless heating comprises a tobacco segment, a cooling segment, a filter segment, a first composite wrapping member, an intermediate connecting member, a tobacco segment wrapping member, and a second composite wrapping member; wherein,

[0009] The tobacco segment, the cooling segment and the filter segment are arranged in sequence;

[0010] The first composite wrapping member is configured to wrap the cooling section and the filter section, the intermediate connecting member is sleeved at the connection between the tobacco section and the cooling section, and the inner wall of the intermediate connecting member is connected to the first composite wrapping member, the tobacco section wrapping member is configured to wrap the tobacco section, and the tobacco section wrapping member is sleeved outside the intermediate connecting member and slidably cooperates with the intermediate connecting member, the second composite wrapping member is configured to wrap the filter section and part of the cooling section, and the second composite wrapping member is sleeved outside the first composite wrapping member, a first air inlet notch is provided at one end of the tobacco wrapping member adjacent to the second composite wrapping member and / or a second air inlet notch is provided at one end of the second composite wrapping member adjacent to the tobacco wrapping member, and the sum of the length of the tobacco section wrapping member and the length of the second composite wrapping member is less than or equal to the length from the free end of the filter section to the end of the intermediate connecting member away from the filter section.

[0011] Optionally, the end of the tobacco segment wrapper is flush with the free end of the tobacco segment.

[0012] Optionally, the length of the portion of the intermediate connecting piece covering the tobacco segment is less than or equal to 1 / 5 of the length of the tobacco segment.

[0013] Optionally, the inner wall of the intermediate connecting member is connected to the first composite wrapping member by bonding.

[0014] Optionally, the sum of the length of the tobacco segment wrapper and the length of the second composite wrapper is equal to the length of the first composite wrapper, and the end of the first composite wrapper and the end of the second composite wrapper are flush with the free end of the filter segment.

[0015] Optionally, the cooling section includes a first cooling section and a second cooling section, and the second cooling section is located between the first cooling section and the filter section;

[0016] A first cooling channel is provided in the first cooling section, a second cooling channel is provided in the second cooling section, and an inner diameter of the first cooling channel is smaller than an inner diameter of the second cooling channel.

[0017] Optionally, the outer diameter of the first cooling section is equal to the outer diameter of the second cooling section.

DETAILED DESCRIPTION

[0030] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0031] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0032] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0033] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0034] like Figures 1 to 4 As shown, the incompletely separated heated cigarette for paperless heating disclosed herein comprises a tobacco segment 1, a cooling segment, a filter segment 4, a first composite wrapping member 5, an intermediate connecting member 6, a tobacco segment wrapping member 7 and a second composite wrapping member 8.

[0035] The tobacco segment 1, the cooling segment and the filter segment 4 are arranged in sequence. In specific implementation, the tobacco segment 1 and the cooling segment may only be in contact without being bonded, and the tobacco segment 1 and the cooling segment are compounded together by the wrapping effect of the intermediate connecting member 6; or, the end faces of the tobacco segment 1 and the cooling segment may be bonded together. The cooling segment and the filter segment 4 may only be in contact without being bonded, and the cooling segment and the filter segment 4 are compounded together by the wrapping effect of the first composite wrapping member 5 and the second composite wrapping member 8; or, the end faces of the cooling segment and the filter segment 4 may be bonded together. The cooling segment may be implemented in a variety of ways, for example, a cooling channel extending along the length direction of the cooling segment is provided in the cooling segment; for another example, the cooling segment has a honeycomb structure.

[0036] The first composite wrapping member 5 can be used to wrap the cooling section and the filter section 4. The intermediate connecting member 6 is sleeved at the connection between the tobacco section 1 and the cooling section, and the inner wall of the intermediate connecting member 6 is connected to the first composite wrapping member 5. The connection between the intermediate connecting member 6 and the first composite wrapping member 5 can be achieved by bonding or crimping.

[0037] The tobacco segment wrapper 7 can be used to wrap the tobacco segment 1, and the tobacco segment wrapper 7 is sleeved outside the intermediate connector 6 and slidably matched with the intermediate connector 6. The tobacco segment 1 is completely wrapped in the tobacco segment wrapper 7. The second composite wrapper 8 can be used to wrap the filter segment 4 and part of the cooling segment, and the second composite wrapper 8 is sleeved outside the first composite wrapper 5. The intermediate connector 6 can be prepared by using a papermaking process to reconstitute tobacco leaves, so as to avoid the intermediate connector 6 being heated to produce a paper smell when the tobacco segment 1 is heated.

[0038] The tobacco wrapping member 7 is provided with a first air inlet notch at one end adjacent to the second composite wrapping member 8 and / or the second composite wrapping member 8 is provided with a second air inlet notch 80 at one end adjacent to the tobacco wrapping member 7. When the tobacco segment wrapping member 7 slides along the intermediate connecting member 6 until the end of the tobacco segment wrapping member 7 abuts against the second composite wrapping member 8, the first air inlet notch and / or the second air inlet notch 80 may be connected to the gap between the tobacco segment wrapping member 7 and the first composite wrapping member 5, thereby forming an air inlet channel between the gap between the tobacco segment wrapping member 7 and the first composite wrapping member 5 and the air inlet notch. In specific implementation, those skilled in the art may choose to provide the first air inlet notch on the tobacco wrapping member 7 or the second air inlet notch 80 on the second composite wrapping member 8 according to actual needs.

[0039] The sum of the length of the tobacco segment wrapper 7 and the length of the second composite wrapper 8 is less than or equal to the length from the free end of the filter segment 4 to the end of the intermediate connector 6 away from the filter segment 4. When the tobacco segment wrapper 7 slides along the outer wall of the intermediate connector 6 until it abuts against the second composite wrapper 8, the tobacco segment wrapper 7 no longer wraps the tobacco segment 1.

[0040] The use process of the incompletely separated heating cigarette for paperless heating disclosed in the present invention can be as follows:

[0041] When the heated cigarette is not inserted into the smoking device, the tobacco segment wrapper 7 wraps the tobacco segment 1, the first composite wrapper 5 and the second composite wrapper 8 wrap the cooling segment and the filter segment 4, the intermediate connecting member 6 is sleeved on the tobacco segment 1 and the first composite wrapper 5, and the tobacco segment 1 is composited with the cooling segment and the filter segment 4 through the sleeve connection between the intermediate connecting member 6 and the first composite wrapper 5 to form a complete heated cigarette.

[0042] When the heated cigarette is inserted into the smoking device to a certain depth, the tobacco segment wrapper 7 stops moving due to the force of the smoking device, and the tobacco segment 1 continues to be pushed toward the heating chamber of the smoking device under the push of the cooling section and the filter section 5, and the tobacco segment wrapper 7 moves along the outer wall of the intermediate connecting member 6 in a direction away from the tobacco segment 1. As the tobacco segment wrapper 7 moves along the outer wall of the intermediate connecting member 6, the tobacco segment 1 and the tobacco segment wrapper 7 gradually separate until the tobacco segment wrapper 7 abuts against the second composite wrapper 8, at which time the tobacco segment wrapper 7 is completely separated from the tobacco segment 1 (such as Figure 3 The portion of the tobacco segment 1 covered by the intermediate connecting member 6 is located outside the heating chamber, and the portion of the tobacco segment 1 not covered by the intermediate connecting member 6 is located inside the heating chamber. The first air inlet notch and / or the second air inlet notch 80 and the gap between the tobacco segment wrapping member 7 and the first composite wrapping member 5 can be used as an air inlet channel when the heated cigarette is smoked.

[0043] When the smoking is completed, the heated cigarette is pulled out in the opposite direction of the insertion of the heated cigarette into the smoking device, and as the tobacco segment 1 moves in the opposite direction, the tobacco segment wrapping member 7 gradually wraps the tobacco segment 1 until the tobacco segment wrapping member 7 completely wraps the tobacco segment 1. Finally, the tobacco segment 1 combined with the cooling segment is completely separated from the smoking device along with the heated cigarette.

[0044] After the heated cigarette of the present invention is inserted into the smoking device, the tobacco segment wrapper 7 can slide along the middle connecting piece 6, thereby exposing the tobacco segment 1 to the outside. Since the heated front end of the tobacco segment 1 is not wrapped by cigarette paper, paperless heating of the tobacco segment 1 can be achieved during the heating process, eliminating the influence of paper smell on smoke, greatly improving the smoking experience. Moreover, after the smoking is completed, the tobacco segment wrapper 7 can slide in the opposite direction along the middle connecting piece 6 during the process of pulling the heated cigarette out of the smoking device, so that the tobacco segment wrapper 7 wraps the tobacco segment 1 again, and the tobacco segment 1 that has not been separated from the cooling segment can be pulled out of the smoking device along with the cooling segment.

[0045] In one embodiment of the incompletely separated heated cigarette for paperless heating disclosed herein, in order to reduce the resistance of the tobacco segment wrapper 7 to the movement of the tobacco segment 1, the end of the tobacco segment wrapper 7 is flush with the free end of the tobacco segment 1.

[0046] In one embodiment of the incompletely separated heated cigarette for paperless heating disclosed herein, the length of the portion of the tobacco segment 1 covered by the intermediate connecting member 6 is less than or equal to 1 / 5 of the length of the tobacco segment 1. This arrangement is conducive to better exposing the tobacco segment 1 during the smoking process, thereby improving the smoking experience.

[0047] In one embodiment of the incompletely separated heated cigarette for paperless heating disclosed herein, in order to control costs and simplify the production process, the inner wall of the intermediate connecting member 6 is connected to the first composite wrapping member 5 by bonding.

[0048] In one embodiment of the incompletely separated heated cigarette for paperless heating disclosed in the present invention, in order to improve the compactness of the heated cigarette structure, the sum of the length of the tobacco segment wrapper 7 and the length of the second composite wrapper 8 is equal to the length of the first composite wrapper 5, and the end of the first composite wrapper 5 and the end of the second composite wrapper 8 are flush with the free end of the filter segment 4. When the heated cigarette is inserted into the smoking device, the tobacco segment wrapper 7 moves along the intermediate connecting member 6 to abut against the second composite wrapper 8, at which time the end of the tobacco segment wrapper 7 away from the second composite wrapper 8 is flush with the end of the first composite wrapper 5 adjacent to the tobacco segment 1, and the tobacco segment wrapper 2 no longer wraps the tobacco segment 1.

[0049] In one embodiment of the incompletely separated heated cigarette for paperless heating disclosed herein, the cooling section includes a first cooling section 2 and a second cooling section 3 , and the second cooling section 3 is located between the first cooling section 2 and the filter section 4 .

[0050] In a specific implementation, the second cooling segment 3 may only be in contact with the first cooling segment 2 and the filter segment 4 without being bonded, and the first cooling segment 2, the second cooling segment 3 and the filter segment 4 may be bonded together by the wrapping action of the first composite wrapping member 5 and the second composite wrapping member 8; or the second cooling segment 3 may be bonded together with the end surfaces of the first cooling segment 2 and the filter segment 4. In addition, the first composite wrapping member 5 may wrap the first cooling segment 2, the second cooling segment 3 and the filter segment 4, and the second composite wrapping member 8 may wrap the second cooling segment 3 and the filter segment 4.
